Technical Field
[0001] This utility model relates to the field of bar stock straightening and feeding technology, and in particular to an integrated automatic feeding device for bar stock straightening in chain link processing. Background Technology
[0002] Chains, composed of individual links, can withstand large axial loads and are a commonly used load-bearing or transmission device in the mechanical engineering industry. Marine chains, offshore chains, and mining chains are all made from rolled round steel, heated to over 700℃ in an induction furnace, and then braided on a link-forming machine. This process has specific dimensional requirements for the total curvature and ellipticity of the rolled round steel. The steel is transported by land, and bending and other damage inevitably occur during transportation, rendering the material unusable. Damage also occurs during unloading after the material arrives at the factory, and similar damage occurs when the material leaves the warehouse. These unusable materials increase material waste and raise costs.
[0003] For the reasons mentioned above, those skilled in the art have developed a bar straightening device for chain link processing, which straightens bent rolled round steel bars to meet usable standards and reduces material waste. Summary of the Invention
[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide an integrated automatic feeding device for straightening bar stock in chain link processing, which improves work efficiency and reduces production costs while ensuring safe production.

The shaping dimensions are adjusted by the primary disc group size adjustment codes and the secondary disc group size adjustment codes. A shearing blade is provided in the machine body at the rear section of the straightener raw material channel, and a size locator is provided at the tail of the machine body.
[0006] Preferably, the warehousing and shaping mechanism includes a first warehousing and shaping shaft symmetrically arranged on the front and rear sides of the corrector raw material channel, and a second warehousing and shaping shaft symmetrically arranged on the upper and lower sides of the corrector raw material channel. The first warehousing and shaping shaft and the second warehousing and shaping shaft are driven by hydraulic motors respectively.
